Abstract

Early recognition of environmental stress factors that may ultimately result in the loss of productivity is essential for economical assessments of agricultural and forestry practices (Moran et al. 1997). Vast resources and management approaches are implemented to increase plant productivity. Rapid noninvasive assessment methods that can detect deleterious environmental effects on crops during early stages of growth in a timely manner would be of great value. A relatively new active sensing technique available for vegetative monitoring is steady-state fluorescence.
